A very rare migrant. I have been able to find but three 

 records of its occurrence within our limits. Mr. Henry K. Coale 

 captured a specimen in September, 1873, at Chicago. In April, 

 1890, I obtained an adult in breeding plumage which was flying 

 with a large flock of Golden Plover (Charadrius dominicus) at 

 Worth, Illinois. Mr. E. W. Nelson says :* "Very rare migrant. 

 A specimen is in the collection of Mr. R. P. Clarke, obtained 

 upon the Lake shore, at Chicago, September 4th, 1873." There 

 is an interesting notation regarding the frequency of this species 

 in Dr. P. R. Hoy's "Notes on the Ornithology of Wisconsin."! 

 With a few exceptions, these notes were based on personal ob- 

 servations made by Dr. Hoy within fifteen miles of Racine, Wis- 

 consin. Racine is but a few miles north of the northern bound- 

 ary of our limits. He speaks of the Buff-breasted Sandpiper as 

 "Quite common from September I5th to October loth. Never 

 met in the spring." I am sure that there must be some mistake 

 in Dr. Hoy's record. Even in 1876, not many years after Dr. 

 Hoy's observations were made, Mr. Nelson was unable to con- 

 firm the report and stated that he thought an error had been 

 made in the record. 



The range of this Sandpiper covers North America though 

 it is more common in the interior. It breeds chiefly in the in- 

 terior of British America and in the Yukon district. In winter 

 it passes through South America as far as Uruguay and Peru.

A very common summer resident and most abundant along 

 the lake shore, where it nests on the drift or under small bushes 

 growing on the sand dunes. This species also nests in thin 

 tufts of grass, and not infrequently the eggs are so exposed that
